The ORAS MCP Server is designed to facilitate communication and management of container images using the ORAS CLI, with support for integration in environments like VS Code.
ORAS MCP Server
Usage
Configure the ORAS MCP Server to run inside VS Code agent mode for registry-aware chats.
The server is implemented with the oras-go
library and does not depend on the oras
CLI.
Setup with Docker
It is easier to use docker to run the ORAS MCP Server.
Setup for VS Code
Add the following code to .vscode/mcp.json
:
{
"servers": {
"oras-mcp-server": {
"type": "stdio",
"command": "docker",
"args": [
"run",
"--rm",
"-i",
"ghcr.io/oras-project/oras-mcp:main",
"serve"
]
}
}
}
Mount Docker credentials (Linux only)
Linux users can share docker login
credentials by mounting the config file:
{
"servers": {
"oras-mcp-server": {
"type": "stdio",
"command": "docker",
"args": [
"run",
"--rm",
"-i",
"-v",
"${env:HOME}/.docker/config.json:/root/.docker/config.json:ro",
"ghcr.io/oras-project/oras-mcp:main",
"serve"
]
}
}
}
Adjust the path if you keep credentials under ${env:DOCKER_CONFIG}
. The container understands only inline auths
entries; helper-based configs (credsStore
, credHelpers
) won't work. On macOS/Windows, install the released binary instead.
Setup from Released Binaries
-
Visit the GitHub releases page and download the archive that matches your operating system and CPU architecture (
oras-mcp_<version>_<os>_<arch>.tar.gz
for Linux or macOS,oras-mcp_<version>_windows_<arch>.zip
for Windows). -
Extract the archive; the folder contains a single executable named
oras-mcp
(ororas-mcp.exe
on Windows) and a copy of the project license. -
Move the binary to a directory on your
PATH
(for example,/usr/local/bin
on Linux/macOS or%LOCALAPPDATA%\Programs\oras-mcp
on Windows) or reference it directly from its extracted location. -
Run
oras-mcp serve --help
(ororas-mcp.exe serve --help
) to confirm the binary works on your system. -
To integrate with VS Code agent mode, update
.vscode/mcp.json
to point at the extracted binary:{ "servers": { "oras-mcp-server": { "type": "stdio", "command": "/absolute/path/to/oras-mcp", "args": [ "serve" ] } } }
On Windows, set
"command": "C:/path/to/oras-mcp.exe"
.
Authentication
oras-mcp
reads credentials from the same stores used by the ORAS and Docker CLIs, but you need to expose those stores to the server process:
- Released binary – Run
oras login <registry>
ordocker login <registry>
on the host machine; the binary will pick up the cached credentials automatically. - Docker container – On Linux you can mount your Docker config as shown in the credential section; ensure the file contains inline
auths
entries. Docker Desktop (macOS/Windows) depends on keychain helpers, so use the released binary there.
